UNDEBFRAME-REINFORCE.

To all e vkom it may concern:

it known that I, TIiOMAS H. Seamai'oN, a citizen of the United States. of Amemca, residing in the city of Rochester, I

county of Monroe, State of New York, have invented certain new and useful Improvemeats in Underframe-Reinforce,. .of which the following is a specification.

In view of the recently adopted regulations of the Master Car Builders" Association requiring that within a short time all wooden frame cars shall be provided with draft timbers extending back of the bolster,

the production of an economical and efiicient system of metal reinforcement for. such cars whereby they are brought within the terms of these requirements or taken out of the class of wooden. underframes and so braced and supportedthat the capacity to resist' the stresses .to which they are subjected un- .der modern conditionsof freight traflic is imparted to them has becom'e an objective fif great importance to the"-v designers of present instance, in place of the wooden center sills which extend from end to end oft-he car, two metal channels or substitute freight cars, and such is the purpose of this invention. To thls end I provide, in the sills of the samelength as the wooden sills, the original sills being removed and re placed by theinetal channels. 'In COYTHGCf tion with these, in the preferred form of my invention I use thin wooden strips to which the floor boards of the car "are fastened and which, in turn, are supported and given'the .requireddegree of rigidity by the channels. The metal channels, or substitute sills, WlllClt have their webs vertical and thee'dge flanges as shown turned outward, extendover and rest on the bolsters helix; reinforced ,at this point preferably by she sections of channel iron or the like, riveted to the substrtute sills. At the endsfl provide draft sills shown in the forin of short sections of channel bar,

depending from the substitute sills and hav ing their webs vertical, the web of each-channel being preferably in the plane of the web of the corresponding sill. The top flange of each draft sill member is secured-to the bottom flange of-the long channels .or substitute sills. As thus arran ed, the substitute construction at the en s presents two vertical, longitudinal surfaces placed, apart preferably by a distance slightly greater Specification of Letters Patent, P te ted July 25, 1916. Appfiestion filed November 80, 1914. Serial No. 8743321 i thanthat which. separated the old wooden utilized. As these have lugs to engage the -Wooden's1lls, seat ng members in accordance with my co-pendlng application, Serial No 871,278, are provided. In the present instance, the structure may be strengthened by having these seating members extend upward above the fcheek plates he that they 'may be secured to the upper channels forming the substitute sills, as well as tothe lower channels which in eifect form the draft sills. ,l Vh1-le, inithe preferredform of the invention, these extensions which are secured to the upper channels, are a portion of the seatin member, they may be madeintegral with 1; 1e cheek plates so thatthe cheek plates themselves are secured both to the upper channels or center sillsfand to the lower channels or draft sills.

In order that the invention may be fully understood, it is illustrated in the preferred folxkmh in the accompanying drawings, in w 10 Figure 1 is a top plan ofzthe back-bone of the car, built up as described, the plamb'eingj broken away .at one side at one endto illustrate one check plate-in sect1on; Fig. 2'is a section taken intermediately of'the car. as at,

2,2 of Fig. 1; Fig. 3 is a section on the line- 3, 3 of Fig. 1; Fig. 4 is a'view, correspondingto Fig. 3, of a slightly modified form 0f the invention; Fig. 5151a view in elevation taken from a point between the center sillslooking outward, showing'one. sill and the Referring to the drawings by numerals,

the device as illustrated consists I of subchannels having their top flanges 5 secured to the bottom flan es 6. of the channels 1, the vertical inner aces 7 of both channels being in the same plane which is also the plane of the inner face of the strip 2. The substitute sills 1 bear at their ends against correlated'parts in elevation and Fig. 6 is a section on the line 6, 60f ig. 5.

the end sills 15 at which point angle 16 may be secured to the sills providing a flange to engage the timber. The sills also reston and cross the bolsters 8 at which point they are reinforced by any suitable means as shortchannel sections 9 secured to the backs or inner-faces T of the channels 1. The draft sills 4; referred to as having their top flanges secured to the bottomflanges of the channels 1 are placed at each end of the substitute sills and tied t gether at the rear by plates. H conneetin; the. bottom flanges.

To the inner faces of these channels, the cheek dates 10 are secured.- l'hcse may be a of any type but preferably the original cheek plates taken froin the woodensills are used.

To provide-a suitable seating surface for these, I preferably use seating members 11 suchas are described in my co-pcnding application, but in the present instance, these may be extended upward above the cheek plates and abo et-he draft having their upper extreir iities lfl secijired to the substitute sills 1 or. as shown in Fig. 4, a new type of 1 -heelc ]';late maybcused having" tongues or flanges .13 secured to the sills while the ody of the cheek plate proper is secured tothedraft sills or channels 4.

It will be 'a'ppiuent that by use of the structure described \'vhich constitutes the back bone of the car,- replacing the wooden sills which'have beenfound wholly insufib cieiit to withstand the usage touvh-ich they are subject under presentconditions, the defects incident to wooden tinderframes. such as the breaking down ofth'ezisills acre the bolster, pulling out of-the'fastenings which hold the cheek plates, and the like, are

wholly eliminated The sulistitute sills are reinforcedat the bolster and the cheek plates are"provided with anflamply. sufficient support in the form of a depending channel sccured'to the l'iotto'm-flange of thesubstitute sill. At the same time, the cheek plates themselves, or the "seating-'members which hold them, -are not only secured to .the bottom channel'or draft beam, but may be pro- \ided with additional means engagin the secured to both membeisgiving substitute sills whereby the cheek plates are equaled rigidity.
